In the process of water well drilling tools, the drill bit plays a vital role. The quality of water well drilling tools directly affects the efficiency and hole quality of water well drilling tools, and it also affects the service life of water well drilling tools. In the process of drilling the water well drilling tools, the operator should also pay attention to the use of the drill. In order to make water well drilling tools work better, the operator should pay more attention to the following aspects of the drill.

1. After the drill bit of the water well drilling tools is drilled into the structure, the center drilling tool needs to be replaced in time. First, the bottom of the hole needs to be cleaned, and then the residue at the bottom of the hole is blown clean. After the drill stops rotating, water well drilling The drilling tool in the tools is slowly lifted up. It is most suitable when the lifting force is just enough to lift the drilling tool.

2. The drill bit of the water well drilling tools are summarized in the drilling process. It is also necessary to pay careful attention to the follow-up situation of the casing, to understand the specific situation in the hole in time, and to keep the hole clean when necessary, and the water well drilling tools The drill bit must not be pulled out forcefully during the drilling process.

3. The bottom of the hole of water well drilling tools sometimes leaves a lot of residual slags. The rotating part of the eccentric bit will be blocked by the slag, which will affect its gathering production. At this time, it is necessary to deliver compressed air and re-inject the hole. Carry out cleaning, and make the down-the-hole hammer work for a short time, and then resume the lifting operation of the center drill.
